High impact information on Fin Whale

• The comparison between the cytochrome b sequences of the fin whale and Stenella showed that differences in codon positions one or two were frequently associated with a change in another codon position [1].
• Samples were collected from 407 fin whales, Balaenoptera physalus, at four North Atlantic and one Mediterranean Sea summer feeding area as well as the Sea of Cortez in the Pacific Ocean [2].
• To investigate this anomaly we have now cloned and characterized the GH gene from finback whale [3].
• These findings support the hypothesis that fin whales from the two sites belong to different stocks and that cadmium in the organism can be used as a complementary tool in studies of population identity [4].
• Polychlorinated biphenyls (PCBs) and DDT compounds were determined in subcutaneous blubber of fin whales (Balaenoptera physalus) and striped dolphins (Stenella coeruleoalba) from the Mediterranean Sea [5].

Gene context of Fin Whale

• The bullfrog PRL shows the highest identity with sea turtle PRL (75%); lower identities with chicken PRL (72%), pig, horse, and fin whale PRLs (68%), human, cattle, sheep, and elephant PRLs (60-58%), and rat and mouse PRLs (50%); and significantly lower identity with teleost PRLs (about 30%) [6].
• Of the known prolactin sequences, equine prolactin shows closest homology with porcine (93%) and fin whale (87-91%) prolactins [7].
